Family: Unknown, No children

Martin Viessmann was born on Oct. 10, 1953. He completed a degree in business administration at the University of Erlangen-Nuremberg in 1979 and joined the family company, Viessmann, in the same year.

Viessmann was founded by Martin's grandfather, Johann Viessmann, in 1917. After starting as a farm machinery repairman, Johann began building furnaces in 1928 and by 1937 he had moved the business to a bigger factory in Allendorf, Germany, where it remains based today.

His son Hans, Martin's father, took over the business in 1947 and sought the modernize its production facilities. Its new steel furnaces became popular during Germany's economic boom in the 1950s and by the end of the decade the company was making about 5,000 furnaces each year.

Production grew to 40,000 a year in the 1960s and in 1972 Viessmann began selling furnaces made from stainless steel. The energy efficient nature of its heating systems helped spur sales in the 1980s.

Martin Viessmann took over as chief executive of the company in 1993 and he began improving the company's technology and international sales. His son Maximilian Viessmann joined the company's board in 2016.
